Unlike hand mixing, the Malcom SPS Solder Paste Mixer is a non contaminating mixer which utilizes pseudo planetary motion to stir the solder paste. The SPS-1 provides uniform paste consistency regardless of operator skill. The paste temperature rises due to friction, enabling control over the solder paste viscosity. Now a solder paste can be pulled from the refrigerator and ready on the stencil, in less than 15 minutes!

The SPS employs a pseudo-planetary motion whereas the solder paste container rotates slowly at the end of an arm which spins rapidly. The resulting centrifuge force causes the solder paste within the container to repeatedly fold over itself, thereby mixing and softening itself.
